What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
MAIN
conclusionSecondary cell wall-associated CesA genes in Populus have undergone a functional differentiation in expression pattern that may be attributable to evolutionary alteration of regulatory modules. Gene duplication is an important mechanism for functional divergence of genes. Secondary cell wall-associated cellulose synthase genes (CesA4, CesA7 and CesA8) are duplicated in Populus plants due to a recent whole genome duplication event. Here, we demonstrate that duplicate CesA genes show tissue-dependent expression divergence in Populus plants. Real-time PCR analysis of Populus CesA genes suggested that Pt × tCesA8-B was more highly expressed than Pt × tCesA8-A in phloem and secondary xylem tissue of mature stem. Histochemical and histological analyses of transformants expressing a GFP-GUS fusion gene driven by Populus CesA promoters revealed that the duplicate CesA genes showed different expression patterns in phloem fibers, secondary xylem, root cap and leaf trichomes. We predicted putative cis-regulatory motifs that regulate expression of secondary cell wall-associated CesA genes, and identified 19 motifs that are highly conserved in the CesA gene family of eudicotyledonous plants. Furthermore, a transient transactivation assay identified candidate transcription factors that affect levels and patterns of expression of Populus CesA genes. The present study reveals that secondary cell wall-associated CesA genes in Populus have undergone a functional differentiation in expression pattern that may be attributable to evolutionary alteration of regulatory modules.
